NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 753,117, dated February 23, 1904. Application led November 10, 1903. Serial No. 180,549. (No model.)

y To all whom, it may concern:

Be it known that I, JOSEPH DENNIS BRENT, a citizen oi' the United States, residing atcRaymond, in the county of Hinds and State of Mississipphhave invented a new and Improved Nut-Lock, of which the'following is a specification. Y Y

This invention relates .to means whereby a nut may be locked against reverse orunscrewing action on its bolt. Y

The invention consists of the new and simpliied nut-locking means, involving improved construction, arrangement, and combination of parts, which will hereinafter be fully described, and the novel features pointed out in the claim.

Reference is had to the accompanying drawv ings, forming a part of this specification, 'and in which- Figure l is a view illustrating my invention in side elevation and showing it in locked and unlocked position, Fig. 2'is a horizontal sectional view taken on line sa of Fig. 1. Fig. 3 is a transverse sectional view taken on line y y of Fig. l. Fig. 4 is a `'longitudinal sectional view showing a modified form of my invention; and Fig. 5 is a. plan view in illustration of the modied form, the locking-button being shown in full lines at unlocking position and dotted in locking position.

In the practice of my invention splice-bars A may be employed as commonly used at railjoints, having perforations therethrough adapted for receiving securing-bolts B.

On the outside of the `splicebars A, I arrange an elongated plate C, having near one end thereof a suitable perforation adapted for receiving the securing-bolt B. To the other end of plate C, I pivotally secure an elongated turn button D, having its free end curved, as at D'. The free end of the turnbutton may be provided with a transverse bend D2, adapting it in locking position for yielding engagement with the nut D3. In further carrying out my invention I may provide the any suitable lug Fon the plate C.

free end of the turn-button on its under side with a groove E, adapted for engagement with I do not desire to be limited in the use of my invention to the lug and groove just described, since or many uses the bend D2 in the turn -button when in locking position would effect binding action of its free end against the nut D3, and thereby obviate unlocking of the nut by accident or from jarring action. The construction above described may be further modified by providing the securing or bolt end of the plate C with bent teeth,

. barbs, or the like Gr to enter suitable depressions in a metal surface or adapted to be driven into a wood base or beam H.

It will be understood that the plate C may be constructed of thin metal with a struck-up projection C, adapted for engagement with a like-shaped depression C2 in the turn-button D.

The use of my invention will be understood from the above description. With the turnbutton turned down against the nut it is apparent that the latter will be securely locked against reverse turning-on its bolt, and while the groove or recess on the turn button and projection or lug on the plate (lis desirable a turn-button having a yielding engaging end so rendered by its bent portion D2 will engage the nut with friction suilcient to hold it in locking position.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination with the bolt and nut, of a perforated plate adapted to receivethe bolt, a longitudinally-yieldable spring turn-button on the said plate, a projection on the plate and a recess in the turn-button, substantially as described.

JOSEPH DENNIS BRENT.
